fix zfin links to no longer use ZFIN_jump

[nathandunn]

https://agr-jira.atlassian.net/browse/AGR-1350

http://zfin.org/cgi-bin/ZFIN_jump?record=ZDB-PUB-020724-1 should use:

http://identifiers.org:ZFIN:ZDB-PUB-020724-1 if the organization is known (for the ZFIN curie prefix) or

http://zfin.org/ZDB-PUB-020724-1 if not (but I think we always know):

should handle all other cases, as well:

http://identifiers.org/ZFIN:ZDB-GENE-001103-2

This will need to be fixed here: https://github.com/geneontology/go-site/blob/master/metadata/db-xrefs.yaml#L3380
